HELP determining WHEN M2 has been chipped/remapped/dme unit
Discussion
Hello,
I am looking for help to gather evidence of when my M2 (2017) has had its DME unit modified, aka when it was remapped / chipped.
I am very much looking to understand the details around how to evidence WHEN it has been modified. Not IF it has, as I have already discovered it has been modified.
The reason I ask is that my M2 is a used car, and the previous owner is not taking responsibility for selling it to me having been modified, and not announcing it had been modified at the point of sale.
I have not had any luck when speaking to private garages nor BMW dealerships / service centres
Thank you for any help!
This is my first post on the forum, apologies if this topic has already been raised as I could not see it.

UPDATE:
I should have mentioned originally, the car is from an approved used BMW dealership, so BMW have been unhelpful in helping provide such evidence of when it occurred!

Not that many people are going to comment, but these cars don't like being remapped & will usually throw an error code to the same effect - it's a case of hoping no-one has erased the original error code, so you can log in with some specialist code reading software & read the code - complete with a date, time & mileage. However if this code has ever been erased, it'll throw again as soon as the car is restarted - but the original occurrence will be deleted.
I use INPA for this, followed by Ediabas. Other options are available.

Try and call Imran at Evolve to discuss.I am looking for help to gather evidence of when my M2 (2017) has had its DME unit modified, aka when it was remapped / chipped.

He may be able to determine the timing of the first Over Boost event in the logs of the DME.
Just a thought, mind you !
Maybe something like Carly will give you the information you want: https://www.mycarly.com/en/app/bmw/.
Bit easier than IPNA.

I'm in all the M2 clubs, and have mine remapped for two years and never heard this opinion. Sure, the N55 doesn't see great gains, but any proper map on ANY car isn't going to throw a CEL as they are coded out.meady100 said:

I called Imran from Evolve, he says only BMW can access the information, known as 'faster data'. Which is unfortunate because my car came from an approved BMW dealership! So BMW have been unhelpful is sharing this evidence! (I'll update my OP with this, I should have mentioned).
Appreciate the DIY suggestions with apps/software, I'm looking into this.
Also, interesting to read the discussions about remapping.

This story amply demonstrates why these kind of cars should be bought directly from an authorised BMW dealership. Any warranty compromising tuning that occurred before you bought the car would then be down to the selling dealer, with him most likely being required to buy the car back.

Which is exactly the problem the OP is having, but having to prove it was there before purchase. Heartworm said:

"the previous owner is not taking responsibility for selling it to me having been modified"I read that to mean he didn't buy it from a BMW dealer...but if he did then he has zero problems.

I guess the OP is trying to ascertain evidence of when it was mapped to prove to the dealer it was mapped when they sold it.
The OP needs to chip in to clarify....but I reckon:
He bought it privately and has since found out its been modified.
The guy he bought it from, got it from a BMW dealer.
The OP now wants to figure when it was ECU modified.....during the ownership period of the guy he bought it from or was it already modified when the previous owner bought it from a BMW dealer.
BMW probably don't want to help in case it puts the liability on them.

I think the OP has now made it very clear that he purchased this car as a BMW Approved Used Car from a BMW Dealership, himself.He bought it privately and has since found out its been modified.

Apologies for any lack of clarity from my posts.
It is as M5 and cuprabob understood, I purchased a BMW approved used car (M2) from a BMW dealership. The dealership denies any responsibility, including claiming to have asked the previous owners if they modified it.
A bit more information if interesting/relevant, which I didn't want to over complicated the initial request with at the start:
2 weeks after purchase (june 2018) my M2 broke down in dangerous conditions (drive train and cruise control failure on the motorway, leading to power completely cutting off). In short, my local bmw service centre didn't find anything wrong (not the same place I purchased the car from).
The same issue reoccured in exactly the same way around 10 months later, my local bmw service centre then discovered the DME was modified.
Skipping ahead of everything I've gone through with BMW (and the many departments), here I am, trying to gather evidence.

A BMW with a modified ECU should not be sold by a BMW dealer as an AUC car....as it invalidates the drivetrain warranty.
There has been a previous case (noted on M3cutters) where in a similar case an M3 was found by a dealer to have a modified ECU and its drivetrain warranty was invalidated. The owner went back to the supplying BMW dealer and got his money back.

You need to go to the selling dealer and demand a refund or the very least fitting of a new standard engine control unit if the warranty is not void.
If the car is under finance speak to the finance company or ombudsman if you get nowhere with BMW.
The used approved pre-delivery check done by BMW will not show if a remap is installed unless it brings up a fault code which in unlikely as the issue would of been found at the first breakdown diagnosis.
I think you will struggle to find out when the map was uploaded unless you find the tuner who fitted it.

No need for a new DME, just put the current BMW software on the existing one. (Sorry no answers for fixing the OP’s issue)
True, but sometimes a chip is soldered into the DME.Gassing Station | M Power | Top of Page | What's New | My Stuff
